Hi there

With a ./configure --prefix=/usr/local && make, I got the following error output after a while:

FYI also tried with GCC/G++ 3.4. Didn't fix the problem.

Tried older version of flex (2.5.4) and bison (1.35) and this seems to have fixed it. Might be worth highlighting that the code *requires* old versions of these.

I got the error you report above ('yy_current_buffer' was not declared in this scope) with flex 2.5.33-4, but not with the older flex 2.5.4a-7

So you might have more luck with a different (older?) flex.
